When I source the extensible sdk environment:

When I source the classic SDK environment:

arm-poky-linux-gnueabi-gdb hello_world.out --command gdb_init
Python Exception <class 'ImportError'> No module named 'imp':
arm-poky-linux-gnueabi-gdb: warning:
Could not load the Python gdb module from `/opt/poky/2.2.1/multi-v7-ml/beagle-bone-black/sysroots/x86_64-pokysdk-linux/usr/share/gdb/python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.

I would assume that the extensible SDK installs something, the classic SDK does not? Maybe the difference is, that I build a sato-sdk for the extensible sdk while for the classic SDK I just build a sato image?
